HYDRAULIC POWER APPARATUS.

Application filed October 17, 1928, Serial No. 668,965. Renewed August.25, 1926.

This invention relates generally to by draulic power apparatus, havingmore particular reference to apparatus In which a water wheel is drivenby water falling from an elevation, the invention having for an objectthe provision of a novel apparatus of this type with which aircompressing'means is combined to operate in alternation.

tion, and of the objects and advantages thereof, reference will be hadto the following description and accompanying drawing, and to the apended claims in which the various novel fiaatures of the invention aremore particularl set forth.-

Fig. 1 of the rawing is a side elevational view of my improved hydraulica paratus.

Fig. 2 is a detail horizontal sectional view taken on the line 2-2 ofFig. 1.

Fig. 3 is a side elevation of the automatic 7 control valve.

Fig. 4 is a detail horizontal sectional view taken on the line 44 ofFig. 1.

Referring now to the drawing the reference numeral indicates a reservoirsituated at any suitable elevation and receiving water from anyavailable source through a pipe 11. The water is conducted from thisreservoir through a pipe ll to a water wheel 12 located at a distancebelow the reservoir and enclosed within a casing 13. Extending acrossthe casing 13, a short distance from the top and bottom thereof, arepartitions 15 WhlCll serve as 'ournals for the shaft 16 of the wheel 12an which are provided with apertures 15 for the passage of the water.The upper one of these partitions has the apertures therein arranged ina circular form and spaced radially a distance to direct the water uponthe vanes 17 of the water wheel. .The shaft 16 may have a gear 16 orother suitable power transmitting element on the projecting lower endthereof for connection to any device to be driven by the turbine orwater wheel.

The water passing from the casing 10 may be carried through a conduit 20to a receiving tank 21 and may be utilized for any desired purpose, adraw-off pipe being indi (rated at 22. I may also utilize the water tocompress air in a second tank 23 here shown as located beside the tank21, and tothis end a branch 24 leads from the pipe 11 downward to thetank 23 communicating with the lower part thereof. Upon this ipe 24 is avalve 26 which is located slight y above the 27 is placed on the pipe 11just under the .point where the branch 24 leads therefrom,

so that when this valve is closed the water may be prevented fromflowing to the reservoir 10 and directed along the pipe 24-. The valves26, 27 are preferably arranged to opcrate inversely in unison so thatwhen one is For further comprehension of the 1nvcn-' closed the other isopened. and this is here effected by means of a rope 29 looped overpulleys 30 on the stems of the respective valves, thisrope being ledaround suitable guide pulleys 31. A nipple 32, controlled by a valve 33,is fitted on'the upper part of the tank 23. This nipple is adapted tohave connected thereto a pipe or tube for conveying the com ressed airaway from the tank.

I prefera ly arrange means whereby the valve 26 is automaticall closed,and the valve 27 opened, when t e air pressure in the tank 23 reaches acertain selected point and to this end a cylindrical housing is mountedon the top of the tank in communication with the interior thereof andhas a iston 36 therein provided with a project- 1ng rod 37 which isadapted to bear upward on a lever 38 fulcrumed at one end on a standard39 on the tank 23, and having at its opposite end in operative relationto the stem of the valve 26. Upon the lever a weight 40 -is hung and maybe adjusted therealong to vary the pressure at which the valve isclosed.

The valve 26 is illustrated in detail in Fig. 3 and comprises a casingin which is a rotary and slidable plug member 42 having the usual port43 therein, stems 44 ad 45 projecting from opposite ends of this mem berthrou h the casing walls, the stem 4.4 having a andwheel 46 thereon andhaving an expansion spring 47 coiled therearound and acting to hold theplug in position, longitudinally considered, in registery with thepassages 48 in the valve casing; Upon the end of the other stem member45 is fixed the pulley 30 and a cam disk 50 and between this disk 50 andthe casing a second cam disk 51 is mounted freely on the said stemmember 45 and has fixed thereto a gear segment 52 meshing with anothergear segment 53 on the end of the lever arm 38. When the air pressure intank 23 reaches the desired point the cam 51 will be caused to rotateand will close the valve by moving the port 43 in the plug element 42axially out of registery wit the passages 48 in the casin Rotation ofthe plug element during t is movement is prevented by a bellcrank latch55 carried by the handwheel and normally engaging in a notchedprojection 56 on the casing, a spring 57 holding the latch in thisposition.

Having thus described my invention what I claim as new and desire toprotect by Letters Patent of the United States is as follows:

1.1m a hydraulic power apparatus, a water wheel, a supply pipe leadingthereto from an elevated point, a closed tank, a by-pass pipe leadingdownward from said first pipe and connecting with saidtank near thebottom of the latter, valves on the respective pipes connected to oneanother to operate inversely in unison, and a device arranged foroperation by the aircompressed in said tank as the water flows from saidhy-pass into said tank, to open the valve on the first named'pipe andclose the valve on the other pipe.

2. In combination with a pipe, a valve on said pipe/including a plugadapted both for rotary and axial movement between open and closedpositions, a handle on said plug for moving the same in a rotarydirection, a cam element for moving the plug axially,

and a releasable member locking said plug 1 against rotary movement.

In testimony whereof I have afiixed my signature.
